db_qd_internal_load_queries (private)

 db_qd_internal_load_queries file_pointer file_tag

Defined in packages/acs-bootstrap-installer/tcl/40-db-query-dispatcher-procs.tcl

Load up a bunch of queries from a file pointer The file_tag parameter is for later flushing of a series of queries when a particular query file has been changed. DRB: it is now used to track the mtime of the query file when loaded, used by the APM to determine when a package should be reloaded. This code depends on the file tag parameter being set to the actual file path to the query file.

Parameters:

file_pointer
file_tag
